Nature of problem: Calculation of dark matter profile from kinematic data, k to view the MathML source">γ-ray and k to view the MathML source">ν signals from dark matter annihilation/decay.
Solution method: Solve the integro-differential Jeans equation (optimised for speed) for several generic distributions (dark matter profile, light profile, velocity anisotropy). Integration of the DM density (squared) along a line-of-sight for generic dark matter haloes with substructures (spatial, mass, concentration distributions). Draw full skymaps of k to view the MathML source">γ-ray and k to view the MathML source">ν emission from dark matter structures, smoothed by an instrument PSF using HEALPix tools.
Reasons for new version: Many more functionalities and options have been added to the code.
Summary of revisions: Inclusion of the PPPC4DMID spectra for gamma-ray and neutrino fluxes; HEALPix pixelisation for skymaps and angular power spectrum; DM profile triaxiality enabled; More mass–concentration options; Multi-level substructure boost; Jeans analysis module to compute dark matter profiles for stellar kinematic data; Improved ROOT and FITS output.
Restrictions: The diffuse extragalactic contribution to the signal (and k to view the MathML source">γ-ray attenuation) as well as secondary radiation from dark matter remains to be included in order to provide a comprehensive description of the expected signal.
Running time: This is highly dependent of the user-defined choices of DM profiles, precision k to view the MathML source">ε and integration angle :
